A few computer clicks is all it takes to learn if you were a victim of the Sony Pictures hack attack, but be careful.

Gizmodo has a created a form where you can type in your e-mail address and see instantly whether the LulzSec hackers know where you live, your date of birth, phone number, and more.

Sony confirmed in a statement that a group of criminal hackers known as LulzSec claimed to have breached some of its websites. Sony said a breach had indeed occurred and the company has taken action to protect against further intrusion.

LulzSec claims the hack exploited extremely basic deficiencies, such as storing passwords in plain text rather than encrypted.

It's not clear from Gizmodo's write-up if they have access to all LulzSec's hacked data, which includes more than 1 million records, or whether it's the 51,000 or so account details already released and freely available.

The hackers apparently were only able to download a portion of what was available. Users of SonyPictures.com are left hanging as to whether their personal details are part of the haul.

There may be a far better way of checking user details against stolen data, as was illustrated by security researcher HD Moore, who provided a way for users to check their data against the Gizmodo theft. Moore required users first encrypt their data on a third-party website before checking it against a publicly accessible Google Docs spreadsheet that contains similarly encrypted data. This way no data was revealed, nor was anybody able to log it.
